TESTING FUEL PUMP DRIVER MODULE DRIVER
The Fuel Pressure Driver Module (FPDM) provides voltage control to the fuel pump to regulate fuel pressure by starting and stopping the pump to maintain fuel pressure. I'll be driving 6 hours each way for Thanksgiving and don't want any problems so any opinions/advice/warnings would be appreciated. I need it? (the emergency shutoff relay is separate from this module and is still connected.) I've been driving it for the past three months since leaving the dealer without a FPDM, but short trips, no more than an hour at a time.ĭo I really need to replace this thing? what is it supposed to do? will I damage the car driving without it? Is it some sort of safety device? Why do Fuel gauge, mpg and range are all working accurately. In the mean time, the car starts right up and runs perfectly, there are no codes or check engine lights. So far I haven't had much luck finding a 96 continental in a junk yard, and don't want to spend $400 or more for a new module. I decide to look for a FPDM in a junk yard and drive the car home with the FPDM bypassed. They also mention that they by-passed the FPDM to get the car to run. $1,500 later, they've installed a new computer it still won't run, they tell me I need a new fuel pump, then later say fuel pump is fine, the Fuel Pump Driver Module needs to be replaced and will cost another $700. Local mechanic couldn't get any codes, took it to dealer, they told me I needed a new computer. machine, you might have to take it to a Ford dealer.My 96 Continental started acting up, running rough, refusing to start, cutting off etc. After several weeks of diagnostics on the car, my mechanic felt it was the module, but had to take it to another shop that has the Ford dyno machine for them to verify that it was the module and to flash the new one to my car.įYI, unless you can find a independent shop that owns a Ford dyno. machine, it is almost impossible to actually pin point the fuel problem. My mechanic stated that unless you have the Ford dyno. Now it is working at 45 Psi with the new module. The module only let my car run for about 10 minutes and then it would die out, at max it was only producing 20 psi. So I did not see the exact location, but they told me that's wear it was located. To be honest, at the point that they replaced my module and flashed it to my car, my car was in a shop, I tried to figure it out myself, but 2 new fuel pumps later, I had to take it in. The covers just pull off and in the center area of the car behind the seats, should be the module. Is this correct? If so, where does the transfer pump fit in?Īfter trying to determine myself the low fuel pressure issue, I had my complete fuel system worked on by my Go To mechanic and was told the module was bad and is located behind the seats behind the covers on the rear cabin wall. k/f090.pdf shows the FP being connected directly to pins 11/12 of the REM.
TESTING FUEL PUMP DRIVER MODULE MANUAL
Given that it is in the trunk of a lincoln LS (and that I can't find it under the Bird), I'm guessing that the manual is wrong.Ģ) Wanted to check the wiring diagram before I started to run electrical tests on the Fuel pumps but the CD does not appear to have a wiring diagram that shows the fuel pumps. The manual says that it is on the underside of the body which is how it is mounted on an F150. Bought the 2002 complete service manual on CD and have two problems.ġ) cannot figure out where the FPDM is located and don't have a picture of it in the manual. Codes suggest possible problem with shorts, the Fuel Pump Driver module (FPDM), or of course the fuel pump. After replacing the blown spare, cleaning up the shards from the tire belts and installing a new battery, the 2002 Bird runs at most for 30 seconds.
